Float type level switches

FL-H series
FL-H series
Horizontal installation float switch made of SUS

Turned on/off by changing the installation direction.

  • For liquid

Other coupling methods (various flanges, ferrules, or screw-in items) and pressure withstand types are also available. The series can be made intrinsically safe and explosion-proof by combining it with a relay isolator.

 

Operating principle
